I surely am not the first to request the enhancement to have view-only users have the ability to filter reports the way they can filter sheets. Without the ability to filter, a report (especially a lengthy one) is not very helpful. I am the Director of Product Development with McGraw Hill Higher Education and my group recently partnered with Smartsheet to build a solution for a new project management office. The reports that can be built on the information in underlying sheets are not ideal due to the filtering constraint. Please strongly consider implementing this enhancement. Thank you!
